The capital can't be conquered. To conquer a village you must:
- attack with army and catapults to destroy the army and residence.
- attack with Senator / Chief / Chieftain many times until the loyalty is 0%.

If in this time the player who is in defense make again residence the loyalty will grow and you will have to destroy again the residence.

Attention : some players can build palace and not residence but without transform that village in the Capital.

    You could attack with Senator / Chief / Chieftain from many villages to take that village from the first try. If you attack with a group of 2 Senator / Chief / Chieftain from the same village you can take down the loyalty of the village more quickly than like if you attack with 2 groups of one Senator / Chief / Chieftain.

    After the loyalty become 0% the village can be yours and the senators will be lost(die). If you attack with a group of 2-3 only one from them will die.

Attention: you could not conquer a village if you do not have enough Culture points.

    After the Village was conquered, this lose 10% from his population, the wall , all trope's upgrades, all researched troops and all army from that village. If you make a party in village from where you send the Senators / Chief /Chieftain the percentage of lost loyalty is bigger.
